6. Vitamin D

Sunshine helps the body sustain the hair growth cycle, but the benefits actually come from vitamin D. Vitamin D deficiency often causes hair loss. Sunlight stimulates vitamin D production, but many fortified and natural foods also contain vitamin D. Unfortunately, UV radiation in direct sunlight damages hair. Enjoying the outdoors and summer sunshine is appealing, but eating a balanced diet or taking a supplement are safer choices to increase vitamin D intake. Hair and skin should be protected in direct sunlight.
